Abstract (en)

[origin: EP3282755A1] A method and system for switching a relay node are provided. The method comprises: a source base station of a D2D relay node or a MME sends the relevant information about the D2D relay node to a target base station, and the target base station perform a corresponding process according to the relevant information about the D2D relay node. The problem of low continuity of communication services of a D2D UE accessed by a relay UE in a process of switching relay nodes, namely, relay UE cells, is solved, thereby improving the continuity of the communication services of the D2D UE accessed by the relay UE during switching of the relay UE cells.
